There was no love lost between Marco Rubio and Donald Trump on the presidential campaign trail, but the Florida senator tells CNN he took it too far with his "small hands" comment—and that he walked it back personally to Trump. "I actually told Donald—one of the debates, I forget which one—I apologized to him for that," Rubio says. "I said, 'You know, I'm sorry that I said that. It's not who I am and I shouldn't have done it.' I didn't say it in front of the cameras, I didn't want any political benefit." In a further change of tune, Rubio says that he'd speak at the convention for Trump, and as for his negative tactics, "I don't think he should change if he's been successful. I may not like that direction, but at this point, he won and this is the direction that he won on." (Meanwhile, Rubio says he's not running for re-election out of respect for a friend.)
